Controlling image capture
Controlling image capture
Which new sequence mode features are available?
New features:
• Repeat one step of a sequence n times where n can be set by the variable
ImageRepeat in SEQUENCE_PARAM.
• Define one or two hardware inputs in Input mode field of IO_INP_CTRL
as:
– Sequence
step input (if two are set as input, they are AND gated) or
– Sequence reset input
Setup mode
The SetupMode flag allows you to set up a sequence while capturing images.
Using this flag you get a visual feedback of the settings. Set this flag when
setting up the sequence and reset the flag before using the sequence.
I/O controlled sequence stepping mode
The I/O controlled sequence stepping mode can be done level controlled or
edge controlled:
The I/O controlled sequence stepping mode can be set for every single
sequence entry. Thus a sequence can be controlled in a very flexible manner.
Note

From now on:
sequence step is I/O controlled sequence stepping mode
sequence reset is I/O controlled sequence pointer reset
Level controlled Edge controlled
• As long as the input is in high
state the sequence pointer will
be incremented from image to
image.
• Can be combined with Quick
Format Change Modes. See
Standard Parameter Update
Timing on page 153 and New:
Quick Format Change Mode
(QFCM) on page 153.
• Level change is asynchronous to
image change.
• A rising edge on the input will
cause one pointer increment
immediately.
• Can be combined with Quick
Format Change Modes. See
Standard Parameter Update
Timing on page 153 and New:
Quick Format Change Mode
(QFCM) on page 153.
